This email is in response to a PR which adds an EFA specific extension:
My question to the group is, what policy should we use for exporting provider specific definitions to applications?
Option 1 is a provider specific header file. For example:
Given the contents, this option makes sense for usnic.
However, there are cases (e.g. PR 7054), where the extensions are minimal. Given that provider extensions have been rare, I propose using fi_ext.h. This would make it easier on the apps, and provide better visibility in the definitions to avoid unnecessary overlap between providers (to help avoid application coding errors).
A third alternative is for very simple extensions to be defined in one of the main header files (e.g. fi_endpoint.h). This option would work for PR 7054.
